IMPROVEMENT IN HEDGE-TRIMMER.

rro ALL WHOM IT MAY CONCERN:

Be it"knownthat I, FRIEDERIGE BINDER, of the city and county of Baltimore, and State of Maryland, have invented a new and improved Hedge-Trimmer; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings forming part of this specification, and in which the figure represents a perspective view of my invention. I

In this invention the cutting blade ismade with a perfectly straight edge, and whon'closed enters a longitudinal slot in the opposite blade, which is also straight. ,My improved instrument is shaped very much like a pair oi' stout shears, both cutting blades" having edges perfectly straight. They are not pivoted like a pair of shears, however, one alongside of the other, but one passes through a slot in the other, 'and is pivoted on a pin which passes through both blades. I

In order that others skilled in the art to which my invention appertuins may be enabled to make and use the same,-I will proceed to describe it in detail.

In the drawings, A represents the single cutting blade, and the double slotted blade, the slot beinglongitudinalin the edge of the blade, and passing through from one side .to the other. The slotted blade therefore presents'two cutting edges parallel to each other, and just far enough apart to allow thecutt'ing edge of the other, the single blade 4, to enter it to the depth of an eighth of an inch, or thereabouts. C is the pivot, upon which the blades work, and Dare the handles. E E are shoulders, which prevent the blades from closing beyonda certain point.

. I have herebefqre secured Letters Patent. upon an instrument having aslotted blade, witha single blade operating in the slot, for the purpose of pruning vines and other heavy work. In that instrument'the cutting blade is convex, and short, like the common eraser used on paper, and the opposite or double blade is highly convex, and is serrated. Such an instrument is useful for simply lopping ofi branches, as in pruning grapevines, or cutting oii'the surplus branches from apple trees, &-c. Forthe purpose sub'served by the peculiar construetion ofmy. trimmer, however, that bi trimming heilges, sl1rubl1ery,:&c., so as to give the shrubs a. smooth and beautiful appearance, the convex and concave-bladed instrument is inedicieut. Such purpose requires a long straight blade, which is to be worked by handles held in the hand-like a pair of tailor'sshears. The work has to be done 'with great care andprecisiom and often the lines left after trimming are to be perfectly straight, as in trimming hedges with flat tops and straight or flaring sides. For-all fine and fancy trimming like this, the straight-edged blades are'indispensable, and it is my purpose to combine theiradvantsges with the advan tn'gesarising from the use of the. slotted blade.

Having thus described my invention, what-I claim as new, and desire to secure by Letters Patntjis- The straight-edged singleblade A, operating in combination with. the straight-edged double or slotted blade- B, substantially as and for the purpose described. a v
